Not So Nifty Fifty

I cannot recall a time when I was this upset with myself. I’m not a doctor, but I feel my background should have allowed me to piece together the clues and help come up with a differential diagnosis much earlier. The perfect opportunity to participate in my healthcare by joining in the discussion and raising the right questions.

Lorie and I made a trip to Memorial Sloan-Kettering Cancer Center’s (MSKCCs) urgent care center last Tuesday (11/6/18). This was due to a fever and breathing difficulty both after going up/down stairs and following coughing episodes. Consider what was known at the time:

  1. X-ray at urgent care suggesting pneumonia
  2. Shortness of breath
  3. Non-productive cough
  4. Low-grade fever
  5. History of radiation therapy to lungs in late July/early August

Pneumonia is a bacterial infection that inflames the air sacs in one or both lungs, but a subsequent CT scan and blood work didn’t confirm. Nonetheless, to be safe and in the absence of any other condition, I was prescribed one week’s worth of the broad spectrum antibiotic levofloxacin (Levaquin®) and instructed to follow-up with my oncologist.

During the following week, all of the symptoms persisted. Between the breathing issues and fever, I didn’t feel like doing much other than resting on the couch all day and writing. Thankfully, I did manage to rally for an early birthday barbeque celebration this past Sunday. Then again, perhaps I jinxed myself by celebrating and posting early! Right, @23aloha? 😉

Aside from the aforementioned, recall that I’ve been suffering from back pain due to the progression of cancer to the spine. In early October, I met with a neurosurgeon at MSKCC in advance of receiving targeted radiation to two areas of my spine. To help prevent or minimize the pain flare that is common following radiation treatment to the skeleton, the neurosurgeon prescribed a steroid (dexamethasone).

Among other side effects, patients who are on steroids for three-weeks or longer are more susceptible to infections than are healthy individuals per the product prescribing information. After finishing radiation treatment to my spine on October 18th, I inquired with my health care team at MSKCC and began gradually reducing my dexamethasone dose to zero beginning on November 1st and finishing on November 6th (hint: day of my trip to urgent care, didn’t seem relevant at the time).

As referenced in my prior post, I’m not a big “birthday” person, but I was looking forward to celebrating my 50th milestone this past Monday. I hoped that the antibiotic would work and I’d be feeling somewhat better by then. No such luck. In general, I felt worse that day, and by the evening my temperature jumped to 101.9 Fahrenheit. No restaurant celebration or interest in my favorite ice cream cake (Figure 1). I took two acetaminophen, which brought the temperature down, and made an appointment the next afternoon to see my oncologist, Dr. David Pfister, and Nicole Leonhart, ANP, RN.

Of course, it wouldn’t be a commute between home and NYC without experiencing some significant delay. This time, a tugboat struck the Portal Bridge and we were held for close to an hour as the bridge was inspected for safety. We arrived at our appointment an hour late, but MSKCC was very accommodating.

After reviewing a new chest x-ray, my medical team offered a differential diagnosis of radiation pneumonitis based on empirical evidence. As soon as I heard the words, it made perfect sense. How could I have missed that! I knew radiation pneumonitis was a potential risk.

Radiation pneumonitis and pneumonia share many clinical features, including inflammation of the lung(s). Radiation pneumonitis is one of the most common toxicities of stereotactic body radiation therapy (SBRT). Most cases are either asymptomatic or manageable, with the reported rates of symptomatic radiation pneumonitis after SBRT range from 9% to 28%. However, most patients develop late pulmonary toxicity characterized by localized pulmonary fibrosis (scarring) in the region receiving the high-dose.

Sure enough, the suspicious areas on my chest x-ray correlated almost exactly with the areas targeted with SBRT over the summer. The sudden appearance of symptoms corresponding with tapering of the prior steroid dexamethasone also provided an important clue. It is likely the steroid meant to address potential bone pain flare issues was also treating the radiation pneumonitis. When I stopped the dexamethasone, the radiation pneumonitis was left untreated and suddenly became symptomatic. Ta-da!

The good news is that with adequate steroid treatment, most patients achieve complete recovery from their symptoms. As a result, I was prescribed an initial two-week supply of another steroid (prednisone). But a diagnosis of pneumonitis does increase the risk of developing subsequent pulmonary complications, including fibrosis, a permanent scarring of the lungs.

While it wasn’t a perfect birthday in the traditional sense (whatever that even means), I prefer to focus on the fact that Lorie, Rosie, and Megan (and the zoo!) were with me on this 50th milestone, and that the recent symptoms weren’t due to further cancer progression (my initial concern) but rather a manageable radiation treatment side effect. Honestly, that is the best gift I could have received.

I would be remiss if I didn’t also acknowledge how important all of the happy birthday calls, texts, gifts, and social media posts were to me. It is one thing to hear from family and friends, but some messages from people I’ve never met in person were also truly lovely and brought a smile to my face. I do read EVERY post! So, to everyone who took time out of their day to acknowledge my birthday—thank you from the bottom of my heart!

 

Roller Coaster

It’s been a couple of weeks since my last clinical post, so I wanted to provide an update following this week’s NIH appointments.

Michael Becker pleural effusion
Xray images of Michael Becker’s chest showing pleural effusion both before and after drainage

First, surgical insertion of my Aspira® drainage system has dramatically improved the pleural effusion in my left lung. It’s essentially a chest tube/catheter that allows me to drain the fluid buildup on an as-needed basis into drainage bags at home. The image to the right shows before and after chest x-ray images that demonstrate just how blocked my left lung was before being drained (nearly 2/3 blocked). It also shows how my left lung is now “close” to normal following drainage.

Second, I’ve been on prednisone (steroid) to help “sculpt” the inflammatory response, which is also helping keep the fluid from building up so quickly in my left lung. Whereas I was emptying 100 mL or more on a daily basis previously, I am now only draining 15-20 mL every other day or so.

Now that the pleural effusion can be managed, attention returned to whether or not to resume treatment with M7824, a completely novel, first-in-class, bispecific fusion protein (see prior posts for more details). My last infusion of M7824 was several weeks ago.

Following another CT scan and constructive discussion with the NIH team, we came to the conclusion that there is essentially a tug-of-war occurring between the cancer in my lungs and my body’s immune system, the latter of which appears to be benefiting from M7824. The hope is that eventually M7824 will tip the scale in favor of my body’s immune system and control the cancer.

Accordingly, the decision was made to keep moving forward with M7824 and I received an infusion on Tuesday, May 16, 2017. As with past administrations, there were no issues and I returned home to Pennsylvania with Lorie later that evening.

The pleural effusion will be monitored closely and managed via the catheter and steroids. As long as there are no major issues in terms of fluid in my lung, I will continue to receive an infusion of M7824 every other week. A repeat CT scan will be done in a month or so to reassess the situation.
